Why should instructors monitor participants' heart rates during class?

Monitoring participants' heart rates during class is essential for ensuring they are exercising within a safe and effective intensity zone. This practice allows instructors to gauge the intensity of the workout in real time, helping to keep participants from overexerting themselves, which can lead to injuries or health issues. Additionally, exercising within the appropriate heart rate zone enhances the effectiveness of the workout, allowing participants to achieve their fitness goals, such as improving cardiovascular health or increasing endurance.

While maximum capacity is important, aiming for this can be counterproductive and risk injury; psychological well-being might be influenced by heart rate but is not the primary reason for monitoring it during exercise; and instant feedback on strength improvements is relevant but does not directly relate to heart rate monitoring. Therefore, the key objective of tracking heart rates is to maintain the right level of exercise intensity for safety and effectiveness.
